1. An acoustic output apparatus, comprising:
a speaker assembly including at least one acoustic driver, the at least one acoustic driver being configured to output sound from a pair of sound guiding holes, wherein
the pair of sound guiding holes are located on a same side of a user's ear canal, and
the user's ear canal and one of the pair of sound guiding holes are disposed at one side of a baffle structure, and the other one of the pair of sound guiding holes is disposed at another side of the baffle structure, wherein the baffle structure increases an acoustic route difference between the pair of sound guiding holes to the user's ear canal.
